A look at cases involving officers charged with misconduct

Many observers were surprised by the swiftness of State's Attorney Marilyn Mosby's decision to charge six Baltimore Police officers in the death of Freddie Gray on Friday, just one day after receiving the results of a police investigation. One lawyer hired by the police union called it a rush to judgment.

Here is a look at the elapsed time between some other high-profile deaths of unarmed black men, and the decision on whether to charge the officers involved.

— Freddie Gray. 19 days. Arrested April 12, died April 19. Officers charged with murder, manslaughter and assault on May 1.

— Walter Scott. 3 days. Killed on April 4 during a traffic stop in North Charleston, South Carolina. Officer Michael Slager charged with murder in the videotaped shooting on April 7.

— Eric Garner. 140 days. Videotaped being choked to death by Staten Island police on July 17, 2014. A grand jury cleared Officer Daniel Pantaleo on December 4, 2014.

— Oscar Grant. 12 days. Shot by a transit police officer in Oakland, California, on New Year's Day 2009. Johannes Meserle was charged with murder by the Alameda District County Attorney on Jan. 13, 2009, and served 11 months in prison after being convicted of involuntary manslaughter.
